TIENet™ 360 LaserFlow™ Velocity Sensor
LaserFlow measures ambient temperature. The microprocessor
program automatically compensates for speed-of-sound changes
caused by air-temperature changes.
The LaserFlow operates with no deadband from the mea-
surement point for both level and velocity measurement.
During submerged conditions, flow measurement continues
without interruption with the optional TIENet™ 350 AV sensor,
which combines continuous wave Doppler to measure area
velocity with a differential pressure transducer to measure level.
The 350 AV sensor is factory-installed on the bottom of the
LaserFlow sensor, and is also available as a kit for installation in
an existing system. Refer to Section 5.7 for kit installation
instructions.
